....2. Related Work The goal of the ULTRA instrumentation is to provide accurate characterization of the intrinsic characteristics of large, parallel message passing programs that can be applied to other computer architectures, rather than to tune performance (e.g. Paradyn [Miller95] Paravision [Nutt95], and Pablo [Reed94] which focuses on identifying performance problems in code on existing computers. Thus, most of the performance tools focus on time based metrics because they try to identify how a program spends 4 10:04:16 October 1, 1999 its time. However, the performance bottlenecks on ....

....has properly terminated. Any number of solutions to this problem are possible: The events can be written to separate files based on process id (this causes other subtle complications in processing and visualizing the events later) The event file can be post processed to remove logical inaccuracies[BS93, NMGM95]; A logical time tracing approach can be used[TC93, TSS94] Perhaps the easiest of these methods is to post process one trace file. Even if the logical time errors are corrected, this approach still has another problem. When the one file is read and visualized by threadview, an essentially serial ....

....is that thread synchronizations may create serialization bottlenecks which are often hard to detect. Removing serialization bottlenecks is referred to as performance tuning. Different tools for visualizing the behaviour of, and thus the bottlenecks in, parallel programs have been developed [1, 2, 3, 5, 6, 9, 10, 11, 12, 14, 16, 18]. The tuning process may benefit significantly from using such tools. Some performance visualization tools show the behaviour of one particular monitored multiprocessor execution of the parallel program [1, 2, 3, 5, 6, 9, 10] If we monitor the execution on a multiprocessor with four processors ....

Some performance visualization tools show the behaviour of one particular monitored multiprocessor execution of the parallel program [1, 2, 3, 5, 6, 9, 10]. If we monitor the execution on a multiprocessor with four processors such tools make it possible to detect bottlenecks which are present when using four processors. The problem with this approach is the lack of support for detecting bottlenecks which appear when using another number of ....

....possibly heterogeneous, tools that cooperate for carrying out one or more analyses of the same parallel program. Tools built by different developers are referred to as heterogeneous tools by Hao et al. 7] An integrated environment may support off line tool usage, such as TAU [2] and ParaVision [20]; homogeneous on line tool usage, such as Paradyn [19] or a combination of the two, such as SPI [1] VIZIR [7] and ParAide [24] Malony [18] presents a classification of measurement based tools comprising four classes: profilebased (sampling) trace based, prediction based, and automated ....

....database approach we propose can be extended to provide support for object oriented parallel codes. Visualization. A great deal of effort has gone into performance visualization. There are a large number of tools on many platforms that provide visual displays of performance data [10] 11] 9] [27]. Similar to data scalability, there is the notion of visual scalability. Most visualizations work well for programs that run for a short time on a small number of processors. As these quantities increase, the visual display becomes less useful and more overwhelming to the user. Support for ....
